Question
In Java, how can we store different types of elements in an array?A) By using Object type arrayB) By using Integer type arrayC) We can’t store different types of elements in the array.D) None of these
Solution
The correct answer is A) By using Object type array.
In Java, arrays are homogeneous in nature, that is, they can only store elements of the same type. However, since all classes in Java are descendants of the Object class, we can create an Object array to store different types of elements.
Here is a step by step guide on how to do it:
- Declare and initialize an Object array.
Object[] objArray = new Object[5];
- Store different types of elements in the array.
objArray[0] = new Integer(5);
objArray[1] = new String("Study Assistant");
objArray[2] = new Double(3.14);
objArray[3] = new Character('A');
